This study analyzes the body shapes of lower-body obese female adolescents and proposes a slacks pattern suitable for their body type. Lower-body obesity is a prevalent type of teenage obesity, and our proposals aim to improve consumer satisfaction in ready-to-wear clothes across this demographic. We first observe characteristics of obese lower bodies, noting significantly above-average thigh and hip circumference. These figures indicate a high degree of curvature in obese lower bodies, along with a large drop value. Leveraging this data, we develop a novel slacks pattern using 3D avatars in a virtual simulation system. The formulas for the main areas of the pattern are as follows: front waist girth W/4+0.75cm+0.5cm, back waist girth W/4+0.5cm– 0.5cm, front hip girth H/4+1.25cm–0.5cm, back hip girth H/4+2cm+0.5cm, front crotch extension H/16+0.5cm, back crotch extension H/8+1cm. Results from appearance evaluations show that this pattern minimizes strain rate on the waist and hips, and its average score is significantly higher than that of an alternative pattern that was also evaluated. The minimized strain rate and high average score indicate that our pattern assigns a sufficient amount of space to the appropriate areas. Based on these results, we expect our research to inform slacks pattern development and production for obese consumers of all types.

This study was conducted to evaluate the risk of overweight and obesity in adolescents consuming snacks frequently from 2007~2009, Korean National Health and Nutrition Examination Survey (KNHANES). The subjects (12~14 years: n=523; 15~18 years: n=614) were presented with food frequency questionnaires, and they were classified according to their gender and frequency of snack consumption. In the age group of 12~14 years, boys and girls (boys OR: 1.11, 95% CI: 0.52~2.39, girls OR: 12.45, 95% CI: 2.26~68.51) who consumed yogurt frequently had a higher risk of overweight and obesity at the highest quartile frequency compared with the lowest quartile after adjustments for multiple confounding factors, including age, physical activity, frequency of eating out and snack consumption, and energy intake. In the age group of 15~18 years, girls (OR: 1.01, 95% CI: 0.34~2.99) consuming fried foods had a higher risk of overweight and obesity at the highest quartile frequency compared with the lowest quartile after adjustments for multiple confounding factors, including age, physical activity, frequency of eating out and snack consumption, and energy intake. Thus, we conclude that frequent consumption of yogurt and fried foods increases the risk of overweight and obesity in adolescents. These findings suggest that the risk of overweight and obesity is associated with the frequency of snack consumption.

This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16, 574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

The purpose of this study was to provide fundamental data needed for running overweight management programs at schools through the analysis of the change of students' life habits and psychological status by applying those programs to them co-conducted by

This study was carried out to investigate the information concerning dietary patterns and analysis of the various factors that influence obesity. The subjects of this study were 1,020 middle and high school students in Seoul. Subjects were classified into under weight, normal weight and over weight group by body mass index. We investigated eating habits, life habits, food behavior and food consumption. Data were collected by questionnair and analysed with the SAS program. The results of this study way are summarized and concluded as fellows; In the case of dietary pattern, over weight group showed significantly higher in skipping a meal than the other group. Also over weight group tend to eat fast. There were significant differences of food intake frequency score by body mass index. From the results of factor analysis of variable related to obesity, 4 factors were generated and the factors were named 'Food behavior related to obesity', 'Snack consumption pattern', 'Life habit', 'Family environment related to food habit'. These factors were associated with obesity. To maintain nutritional balance and health, we should implement to ensure good dietary patterns.

목적: 본 연구의 목적은 저소득층 아동·청소년의 신체 활동에 관한 선행연구를 토대로 신체활동상담 프로그램을 개발하고, 이를 아동·청소년에게 적용하여 그 효과를 검증하는 것이었다. 방법: 인천에 소재한 초등학교 2개교와 중학교 2개교의 재학생 중 저소득층 학생 189명(초등학생 92명, 중학생 97명)이 선정되어 초등학교 46명, 중학교 50명이 실험집단에 배정되어 신체 활동 상담 프로그램이 12주간 진행되었다. 프로그램의 효과 검증은 양적 연구방법과 질적 연구방법을 병행하는 동시적 혼합연구 방법을 사용하였다. 양적 연구에서는 프로그램의 적용 효과를 검증하기 위하여 네 가지 항목, 즉 유연성, 근력, 순발력, BMI를 측정하였다. 신체적 자기개념의 변화를 알아보기 위해 최선인, 정청희, 김병준(2005)의 신체적 자기개념 측정 도구를 사용하였다. 체력검사와 신체적 자기개념 검사 모두 사전 검사, 사후검사, 지연검사를 12주 간격으로 실시하여 이원혼합 설계 분산분석을 활용하여 자료를 처리하였다. 한편, 질적 연구에서는 양적 연구에 참여한 학생 중 무작위로 초등학생 13명, 중학생 12명을 대상으로 비참여적 관찰, 반구조화 개별 면담, 학생 신체 활동일지를 활용하여 문화 기술적 연구를 시행하였다. 연구 자료는 영역분석과 분류 분석의 절차를 통해 자료의 분석이 이루어졌다. 결과: 양적인 연구에서는 4가지의 체력검사와 6가지의 신체적 자기개념 검사별로 이원분산분석을 실시하여 사후검사에서는 프로그램의 효과가 있다는 것을 확인하였으나 지연검사에서는 일부 요인에서 집단별 평균점수의 차이가 없는 것으로 나타났다. 질적 연구에서 학생들은 신체 활동과 영양에 관한 지식, 개인 내적 변화(체력향상, 재미, 건강증진, 학업태도의 변화), 관계향상에서 진전이 있었다고 하였다.

As the number of obese patients increases, childhood obesity also increases and it is recognized as a big problem because it increases the incidence of hypertension, hyperlipidemia, diabetes and metabolic syndrome. Although thyroid hormone abnormalities sometimes exist in obese patients without thyroid disease, there is still much controversy on the impact of obesity on thyroid hormone test results. Accordingly, the present study investigated the correlation between obesity and thyroid hormone concentrations in children with normal thyroid function. In the present study, 356 patients aged 6-18 years who visited the Chosun University Hospital were randomly selected, after exclusion of those with thyroid disease, diabetes mellitus, kidney disease, those with a history of smoking and drinking, and those taking steroids or lipid lowering agents. There were no significant differences in levels of thyroid stimulation hormone (TSH) and free thyroxin (fT4) between males and females. The patients were divided into groups based on serum TSH concentration: group A with TSH < 4.0 μIU/mL and group B with TSH ≥ 4.0 μIU/mL (upper level of normal range). BMI z score, ALT, rGTP, and total cholesterol were significantly higher in group B. Multiple regression analysis adjusted for age, gender, birth weight, and pubertal development showed that TSH and BMI z score were positively correlated, while fT4 was not correlated with other factors.

The aim of this study is to investigate the clinical significance of acanthosis nigricans scales and locations in order to validate the relation of hyperinsulinemia and insulin resistance in obese children. We conducted a retrospective analysis of clinical records of obese children who visited Chosun University Hospital between January 2013 and February 2014 due to their obesity. Five anatomical sites were examined for evaluation of acanthosis nigricans. Clinical characteristics were compared according to the presence and severity of acanthosis nigricans. Among 55 children, 37 children had acanthocis nigricans. A consensus score of acanthosis nigricans was calculated by summing the scores of five locations. The diagnostic categories were: No acanthosis nigricans group, mild group, moderate group, and severe group. Elevated acanthosis nigricans total score showed strong association with elevated BMI, triglyceride, and c-peptide in all groups. Elevated acanthosis nigricans total score also showed strong association with elevated fasting insulin and HOMA-IR. We also found that the neck was the most frequent location of acanthosis nigricans. However, acanthosis nigricans on axilla showed strong association with elevated fasting insulin and HOMA-IR. Estimation of scales and locations of acanthosis nigricans could be useful as a clinical alternative for determining hyperinsulinemia and insulin resistance in obese children.

본 연구는 신체활동과 심리수정을 토대로 한 비만관리 프로그램이 남자비만청소년들의 체중감소와 신체 활동수준 및 심리적 변인을 변화시키는데 효과가 있는지를 확인하는데 그 목적을 두고 수행되었다. 서울시 N구에 소재한 C중학교 남학생중, 체질량이 25kg/m2인 비만학생 86명이 자발적으로 비만관리 프로그램에 참여하였다. 비만관리 프로그램은 12주간 줄넘기 운동 (주 3회)과 심리수정 전략(주 2회)으로 구성되어 있으며, 1회 40분씩 실시되었다. 여가시간 신체활동 질문지, 운동자신감 질문지, 의사결정균형질문지가 연구참여자들의 신체활동 및 관련된 심리적 변인의 변화를 측정하기 위하여 사용되었다. 연구 참여자들의 일반적 특성은 기술분석에 의해 제시되었으며, 비만관리 프로그램의 효과를 검증하기 위하여 반복측정분산분석이 수행되었다. 비만청소년들의 체질량은 비만관리 프로그램을 통해 유의하게 감소 하였고 (F=4.89, p=.007), 신체활동량은 유의하게 증가하였다 (F=3.87, p=.025). 또한, 비만청소년들의 신체활동 자신감(F=4.38, p=.016)과 신체활동이득에 대한 지각 (F=4.07, p=.021)은 유의하게 증가한 반면, 신체활동의 지각된 장애요인 (F=4.15, p=.023)은 유의하게 감소하였다. 본 연구는 비만과학 및 운동과학 영역에서 비만관리 프로그램을 계획하고 적용하는데 있어 신체활동 뿐만 아니라, 신체활동에 영향을 주는 다양한 심리적 특성의 중요성을 고려하여야 한다는 것으로 제안한다.
